High-Efficiency mosfet-Based MMC Design for LVDC Distribution Systems

Design of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications

This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...

Effective Circuit Design Techniques to Increase Mosfet Power Amplifier Efficiency

These impedance conditions correspond to the class F operating condition, the ideal voltage and current shapes for which are shown in Figure 1. Here a sum of odd harmonics produces a square voltage waveform and a sum of even harmonics approximates a half-sinusoidal current shape. In reality, both extrinsic and intrinsic transistor parasitic elements have a substantial effect on the efficiency, ...

FlipFET MOSFET Design for High Volume SMT Assembly

International Rectifier has used a proprietary technique to position all the terminals of a HEXFET device on the same face of the die. This has enabled the development of wafer scale packaged MOSFETs. We're calling the technology platform the FlipFET MOSFET, and we are using it to offer surface mount products with the lowest RDS(on) per footprint area in the industry. This paper introduces the ...

Compressed Domain Scene Change Detection Based on Transform Units Distribution in High Efficiency Video Coding Standard

Scene change detection plays an important role in a number of video applications, including video indexing, searching, browsing, semantic features extraction, and, in general, pre-processing and post-processing operations. Several scene change detection methods have been proposed in different coding standards. Most of them use fixed thresholds for the similarity metrics to determine if there wa...
